Camera on Rail ( 3D Scroller ) [Tutorial][C#] - Unity 3d

[@darksidebidi]

man, i love you for real, this helped me a lot! i need to make a 3rd person camera but camera is fixed on a rail like this so the rail part is done now i need to figure it out on how to keep it on a position behind the player with a certain distance. thanks a lot

[@mesolagic]

This was really helpful! Followed tutorial exactly and it works perfectly still. Instead of having a camera follow my player I needed a 3D spatial audio source to follow my player so I just stuck this rail mover script on there and it perfect! Thanks man!

Thanks a lot. dude you save us. all bless you for the eternity and eons.

cheers :)

[@petemon69]

This is awesome. This is exactly what I needed for my game. Thanks a lot.

[@n3ken]

+petemon69 Glad you like it! I'm upgrading the system a bit, I will release a more versatile version in the upcoming weeks :)

[@johnnymcfettsack3552]

@@n3ken where can i find this upgraded version?

[@master2k27]

Thanks very much! Helped me out alot :)

Hey I'm wondering is there a way to get the camera to follow the player but stay at a fixed distance away from the player using this method

[@GWKTM]

Is there a way to give rail bezier corners?

[@GWKTM]

How to change it so that it can pick a path on intersections?

Hi @N3K EN, I have a few quick questions about your video. First, how are you controlling your capsule character? I don't see any children under it in your inspector so my thought that it has a third person character camera inside is wrong no? Second, I don't understand how your unity environment immediately generates the Grey checkerboard terrain where is that coming from? Thanks for a great video otherwise!

[@niallmccaffrey791]

Is it typical to always have the camera at the closest point on the rail? For instance, your third point is explicitly placed further away, but this camera system jumps over it. Have you also tried keeping track of the current nearest node, and then just testing the previous and next on the rail, to see which is closest? This would scale MUCH better.

Hi, great video! Is there a way to implement split or multiple paths with this? For some reason, I just seem to be unable to figure it out.

I made it exactly like you did in termes of nodes,capsule and ground placement and my camera instead of following my capsule to the left on the direction of the nodes it stands stil when I move left to right , only if I move in a perpendicular way from the line of nodes and in their direction does the camera goes in that direction.Basically the camera is following my character in the wrong direction.Where could I have made a mistake?

[@TheBrownGaming]

May I have Help? Im Getting a Error Saying [19:23:26] Assets\Rail.cs{125,1): error CS1529: A using clause must procede all other elements defined in the namespace except extern alias declarations

[@gutozardy]

Maybe the GetChildCount method is no longer available. I used transform.childCount.

[@n3ken]

This is correct, thank you for the specification

[@armin1888]

Thanks alot for the video! Could u make more comments next time? Alot of things were hard to understand :/

[@n3ken]

For the next big serie, i plan on commenting out pretty much anything, but its not just yet finished scripting

[@asdasdasd9815]

Can write the script in the comments?

[@boshygames2349]

can anyone tell me why my camera is shaking?

[@niallmccaffrey791]

Move the camera first, thn do the LookAt?
